In Aspen Grove Condominium Assoc. v. CNL Income Northstar LLC, (2014) 231 Cal.App.4th 53, the court of appeal affirmed a trial court order requiring the owners of the Northstar Ski Resort to remove a 20,000 cubic foot water retention basin. Northstar constructed the basin as part of a major expansion of buildings, driveways and parking lots. Despite the fact that Northstar had numerous other areas of its property on which to build the basin, Northstar the basis along a lower boundary if its property, close to neighboring buildings, and apparently without sufficient geotechnical or soils analyses.
